Definitions
- Heat applications for medical or cosmetic treatment of humans and animals have been known since ancient times.
- the most original forms of application are wipes soaked with warm water to relax facial skin after shaving, warm wraps for colds, fango packs for muscle tensions or hot water bottles filled with hot water for stomach ailments.
- the two most common basic systems of heat patches are those which release pharmaceutically active substances, an active substance, into the skin and have a physiological action there, eg capsaicinoid-containing products such as Hansaplast® ABC heat patches.
- the second group of heatplops utilizes exothermic chemical reactions, such as the exothermic oxidation of iron as a purely physical source of heat, which releases the heat to the tissue underlying the patch, eg, Hansaplast® Therapeutic Heat Ped.
- a disadvantage of patches with an active ingredient for sensation of heat is that a certain amount of time must elapse before an effective amount of the respective active substance has penetrated from the plaster matrix into the skin.
- the heat sensation differs from user to user, so that thermal plasters of a homogeneously produced batch of a product can be perceived by different users from “not warming” to “much too hot”.
- thermal plasters of a homogeneously produced batch of a product can be perceived by different users from “not warming” to “much too hot”.
- body and external factors such as sports, sauna, waterbeds, air-impermeable clothing, enhance the personal warmth.
- the product is thus only suitable for single use directly after opening the packaging. During use, the products show a fluctuation in the maximum temperature and at the end of the reaction an undifferentiated temperature drop. According to the Japanese Industrial Standard, however, the temperature after 30 min between min. 40 and max. 45 ° C and after 8 hours of use do not fall below 39 0 C.
- the object of the invention is to provide an alternative to the known heat patches thermal paving, which shows a uniform and controllable by the consumer heat development.
- the heat development takes place by means of resistance heating elements based on carbon nanotubes (CNTs).
- CNTs carbon nanotubes
- a suitably equipped plaster reaches its full heat output within 30 to 180 seconds after switching on, the application of a voltage to the CNT heating element and can then within the limits of ⁇ 2 0 C over the entire Keep application duration constant.
- the temperature fluctuation is preferably below ⁇ 10 ° C.
- the heat output of the CNT heating element can be regulated by means of switches or steplessly by means of discrete components or semiconductors.
- thermocontroller it is possible to regulate the heat output via a preprogrammed, integrated into the pavement or external control, so that, for example, certain temperature profiles are achieved or the heating takes place at intervals.
- heating elements made of carbon nanotubes (carbon nanotubes -CNT).
- the walls of the CNT consist only of carbon, with the carbon atoms forming a honeycomb structure with hexagons and three bonding partners each.
- the diameter of the tubes is usually in the range of 1-50 nm and lengths of several millimeters for individual tubes and up to 20 centimeters for tube bundles have already been achieved.
- the electrical conductivity within the tube is metallic or semiconducting;
- Carbon tubes are also known which are superconducting at low temperatures.
- CNTs are made of pure carbon whose individual C atoms are arranged in a grid-shaped tube. These tube structures can be open on both sides, open on one side or closed on both sides. Further, the CNTs may be selected from single-wall, double-walled, multi-walled, functionalized CNTs or CNT bundles, and mixtures thereof. Preference according to the invention is given to multi-walled CNTs.
- CNTs are excellent electrical conductors and heat conductors.
- CNTs have a comparable cross-section about a 1000-fold current carrying capacity over copper.
- the thermal conductivity at room temperature of CNT is about twice that of the diamond and is about 15 times the thermal conductivity of the copper.
- CNTs are commercially available, for example, under the name Millenium-Tube or Millennium-Fiber from the company carbon-NT & F 21, Eisenstadt, Austria.
- Another supplier of CNTs is CNT CO., LTD (Korea), which sells CNT under the name "C-Tube”.
- pulverulent or dispersed, in particular suspended, CNT are brought into a two-dimensional application form as a composite.
- the CNTs may be applied as a thin layer to a substrate and physically bonded thereto, e.g. as a "varnish application,” or by mixing processes are homogeneously incorporated into a matrix system, e.g., as a CNT polymer matrix.
- CNTs may form into a grid structure similar to the structure of an embedded nonwoven web in which the individual CNTs touch.
- a voltage drop occurs due to the contact resistances which occur at the contact points of the CNT, and thus a development of heat.
- a heat paving according to the invention can not only be very thin, but also very flexible. This allows a high freedom of forming the CNT thermal paving both in the manufacturing as well as in the application form.
- This deagglomeration can be carried out via pretreatment of a CNT dispersion, for example via ultrasound treatment by means of a sonotrode.
- a CNT dispersion for example via ultrasound treatment by means of a sonotrode.
- the CNT agglomerates break apart into individual CNTs.
- the treatment conditions must be chosen very carefully, depending on the CNT used, since an excessive ultrasound exposure can lead to a shortening of the individual tubes.
- impurities such as amorphous carbon, catalyst residues, etc. are removed from the pretreated sonotized CNT dispersion. Since these impurities usually have a higher density than CNT primary particles, they can easily be centrifuged off. The supernatant deagglomerated and purified CNT dispersion can then be used directly for the preparation of inventive CNT composites.
- CNT dispersions are preferably suspensions of solid CNT in a liquid matrix.
- the proportion of CNT in the finished composite usually ranges from 1 to 15% by weight, based on the total mass of the composite.
- Such matrices can prevent moisture build-up under the thermal paving and thus lack of adhesion or local overheating effects due to condensation.
- liquid silicones so-called liquid silicone rubbers (LSR), as are commercially available, for example. used by the company BAYER AG or DOW.
- LSR liquid silicone rubbers
- the deagglomerated and purified CNT are homogeneously mixed by means of mixing systems with one or both LSR components, if necessary the dispersant of CNT Deagglomerisation removed and the CNT / silicone mixture by injection molding, extrusion, casting, pressing or other silicone processing in the desired shape for the final product and then polymerized to a solid product.
- the type of crosslinking of the silicones used is insignificant for the end product, as is the molecular fine structure of the silicones or other additives which can be selected according to the application properties of the final heat plaster.
- the final form of the CNT-containing composite can be produced by casting, spraying, injection molding, extrusion, compression molding, etc.
- the layer thicknesses of such CNT / silicone composites can be up to several millimeters. However, thicknesses between 100 .mu.m and 2500 .mu.m are preferred, since they have excellent flexibility and breaking strength.
- thermal patches can also be produced by applying CNT-containing paints or coatings to substrates (support materials).
- the paints or paints can be based on water or solvent.
- the CNT content may be well below 1 wt .-%, based on the total mass of the paint, which greatly facilitates the production of thin homogeneous CNT layers.
- the CNT concentration is again high enough to form enough CNT-CNT contacts and thus show a heat development when applying a voltage.
- General processing can be done with the technologies commonly used in paints and inks, e.g. spray, print, spread or dip with subsequent drying process and / or crosslinking process in reaction coatings.
- CNT-containing paints very low functional layer thicknesses of about 10 ⁇ m to 100 ⁇ m can be achieved.
- Bucky Papers This is a material form consisting only of pure CNT. Another form may consist of a mixture of CNT and paper fibers which are placed in a paper form.
- the matrix in which the CNT is embedded is the adhesive layer of the patch itself. Due to the chemical inertness of the CNT, the molecular basic structure of the adhesive matrix is insignificant. It is possible to use both polar and nonpolar, solvent-borne and solvent-free hot melt pressure-sensitive adhesives as well as aqueous gel matrices (cataplasms).
- the CNT composites described above are provided with electrical contact points at least at two points that are not directly adjacent.
- electrical contact points at least at two points that are not directly adjacent.
- Advantageous are two on opposite sides or directly in the CNT layer integrated electrical conductor tracks. These tracks can be made of metal foils, metal wires, electrically conductive paint or other electrically conductive materials and make the connection point of the CNT to the power source.
- the current source for a thermal paving according to the invention is correspondingly connected via further conductors such as copper cable with these contact points, wherein the current flow can be interrupted or activated via a switch.
- pre-selectable temperatures or temperature profiles can be set by additional control options, such as programmable logic controllers (PLC).
- PLC programmable logic controllers
- Thermal patches according to the invention are supplied via a current source which deliver a maximum voltage of 48 V, in particular between 3 and 12 V.
- the heat patches according to the invention are well below the range of electrically active patches with piezo elements that require a charging voltage of 100 V to 3000 V.
- those based on inventive CNT heat patches are thus significantly more electrically safe for the user.
- Button batteries are preferred, particularly preferably flexible flat batteries or rechargeable batteries, since these are due to their low Easily integrate dimensions into the thermal plaster.
- energy sources in the form of solar cells are possible.
- connections to the power sources of mobile phones, cars and motorcycles may also be provided.

- the carrier material is permeable to water vapor in order to be able to derive excessive sweating of the skin during use.
- This cover film can consist of all commonly used for the purpose materials and the adhesive matrix uniformly over the entire surface or for better removability from two or more, possibly overlapping identical or different materials.
- the CNT layer is not integrated in the adhesive matrix, but incorporated as a separate layer between the adhesive matrix and the carrier material.
- an additional barrier layer of a CNT-impermeable material can be incorporated between the individual layers. This CNT impermeable material can also enclose the CNT composite in total bag form.
